So far, I can only tell if a property is inherited or not, but I need to know the source of inheritance, (for ex, which CSS file caused the final value ?) is this possible ?
Is there a handy tool for this ?
EDIT
Here is what I get in chrome Computed Style (show inheritance)
See the direction property, there is no info about its inheritance source






directionhas a default value in your case. Can you provide an example you are testing this on?element.style { }atstyles panel
